MOUNTING PREPARATION

Inserting or Removing the MicroSD Card

Before mounting a new controller, you must insert the included microSD flash memory card. The microSD card includes the operating system as well as the LG user interface. This card must be installed for the MultiSITE Communications Manager controller to function.

Before inserting or removing the microSD card

• The controller must be unmounted from any DIN rail or screw tab mounting, as accessing the card uses space behind the mounting base.

• Disconnect all power to the controller and use static discharge precautions.

Note:

The microprocessors and associated circuitry within the controller are sensitive to static discharge. Work in a static-free area. Discharge any static electricity you may have accumulated. Discharge static electricity by touching a known, securely grounded object. Disconnect all power to the controller and use these precautions before removing or inserting the microSD card. Otherwise, equipment damage is likely to occur.

MOUNTING PREPARATION

Steps to insert or remove the card

1. Carefully slide the plastic microSD card shutter open. The shutter must remain captive in the base, revealing the microSD card socket.

2. To insert the microSD card, slide it into card carrier, label side up, until the spring catch engages. If properly inserted, the card is behind the shutter track.

3. To remove the microSD card, push it in, until the spring release pushes it partially out of the card carrier. Grasp the card, pull it completely out of the unit and store it in a static free protective case.

4. Carefully slide the card shutter back over the card carrier opening, until it clicks in place. When properly closed, the shutter must not protrude behind the mounting base.

Note:

• Data on the microSD card is encrypted. If you swap in a card from a previously congured unit, you must change the MultiSITE Communi-

cations Manager system passphrase on the platform to match the passphrase on the new microSD card.

• Typically, the microSD card never needs removal. However if a controller has been electrically damaged or found faulty, you can remove

the card and install it in another similar unit, so it can become a functional replacement.

• Yellow (TX): indicates the controller is transmitting data on the V-Net port.

• Green (RX): indicates the controller is receiving data from an V-Net device connected to this port.

These LEDs use a fixed “on time” when a message is detected on the port. If a receive LED is on constantly, this can indicate a wiring problem, such as a shorted wire or reversed wiring.

Due to our policy of continuous product innovation, some specifications may change without notification.

Page 22

STATUS LEDS

STAT (Status) LED

The green “STAT” LED provides a CPU machine status check, and should remain lit whenever the controller is powered. See Figure 10. If the status LED does not light while power is applied, contact Technical Support.

BEAT (Heartbeat) LED

In normal operation, the yellow heartbeat “BEAT” LED blinks at 1 Hz, at 50%/50% on/off duty cycle. See Figure 10.

During controller bootup, this LED may blink at 1 Hz with a 90%/10% on/off duty cycle, or in some other irregular pattern. When boot up completes, the platform daemon starts, and the normal 1 Hz flash at 50%/50% on/off duty cycle returns.

If the “BEAT” LED stays on constantly, does not light, or blinks very fast, contact Technical Support.

Note:

The 1Hz, 90%/10% on/off “BEAT” flash at bootup also occurs during other critical operations, such as a firmware upgrade to the controller and/or any attached modules. Do not remove power from the controller while its “BEAT” LED flashes with a 90%/10% on/off duty cycle. Wait for the normal (50%/50%) flash to return before removing power.
